The report consists of (A) a pass summary, (B) an overview of the analysis results, detailed statistics of the analysed measurements, and an accumulative pass overview and (C) the earth rotation parameter solutions submitted to IERS. The report is based on all quick-look data as received until Mon, Apr 16, 2001. Questions and comments should be addressed to: K.F. Wakker Delft University of Technology Faculty of Aerospace Engineering Delft Institute for Earth-Oriented Space Research Kluyverweg 1 NL-2629 HS Delft The Netherlands Telephone: +31-(0)15-2782065/2785377 Telefax : +31-(0)15-2785322 E-mail : ron.noomen@deos.tudelft.nl A. PASS SUMMARY The table below gives an overview of the ranging data both on LAGEOS-1 and LAGEOS-2, as received by the Quick-Look Data Analysis Center (QLDAC) on Mon, Apr 16, 2001. All data were obtained through the NASA Crustal Dynamics Data Information system (CDDIS) and the Eurolas Data Center (EDC) in Germany. The data are unscreened and may span more than a week due to late reporting by the stations. ------------------------------------------------------------------------------ Station System/Location Period No. of Passes ID LAGEOS-1 LAGEOS-2 ------------------------------------------------------------------------------ 1824 Kiev, Ukraine 010410 - 010411 4 - 1864 Maidanak, Uzbekistan (site 2) 000927 - 000927 1 - 1884 Riga, Latvia 000922 - 000925 2 - 7080 McDonald Obs., Fort Davis, TX 010410 - 010416 5 3 7090 Yarragadee, Australia 010409 - 010416 8 9 7105 Greenbelt, Maryland 010409 - 010415 5 3 7110 Monument Peak, California 010413 - 010413 - 1 7210 Haleakala Obs., Maui, Hawaii 010411 - 010411 1 1 7237 Changchun, China 010412 - 010415 9 2 7249 Beijing, China 010413 - 010415 5 1 7403 Arequipa, Peru (TLRS-3) 010411 - 010416 1 3 7501 Hartebeesthoek, SA (MOB-6) 010410 - 010412 2 4 7806 Metsahovi, Finland 010409 - 010410 4 - 7811 Borowiec, Poland 010410 - 010411 3 - 7820 Kunming, China 010409 - 010415 4 4 7824 San Fernando, Spain 010406 - 010412 6 2 7832 Riyad, Saudi Arabia 010409 - 010411 4 4 7835 Grasse, France 010409 - 010416 10 6 7836 Potsdam, Germany 010412 - 010412 1 - 7837 Shanghai Observatory, China 010411 - 010414 7 2 7838 Simosato Observatory, Japan 010411 - 010413 2 2 7839 Graz, Austria 010409 - 010414 5 2 7840 Herstmonceux, United Kingdom 010409 - 010416 7 8 7845 Grasse, France (LLR) 010409 - 010414 5 3 7849 Mount Stromlo, Australia 010409 - 010416 13 19 ------ ------ --- --- TOTAL 000922 - 010416 114 79 ------------------------------------------------------------------------------ B. ANALYSIS RESULTS The analysis is based on two orbit solutions using global quick-look normal points that cover a period of 10 days which are computed simultaneously. This week´s data interval runs from Thu, Apr 5, 2001 to Sun, Apr 15, 2001. The measurement and dynamic models used in this analysis are close to the IERS Standard. The overall model is referred to as QLDACMOD9. The details of this model can be obtained on request. The terrestrial reference frame is provided by a special version of the SSC(DUT) 93L05 station coordinates solution. The general statistics and results of this week´s analysis are thus: ----------------------------------------------------------------------- Satellite LAGEOS-1 LAGEOS-2 Number of Stations 25 20 Number of Passes 143/139 110/107 Number of Normal Points 1419/1346 1343/1293 RMS of Fit (mm) 34 31 ----------------------------------------------------------------------- Residual statistics per station. The header line for each station shows the station id, its name, whether the position is solved for or not and the measurement accuracy in mm. Rejected observations are not used for the calculation of the rms-of-fit, the biases or the scatter. The latter holds w.r.t. the residual trend line described by the bias estimates. Uncertainties are 3-sigma values. -------------------------------------------------------------------------------- Date Time Sat. Obs.

COMMENTS 1. This is a QLDAC analysis report in a new style. Although our old report served quite well for observation campaigns, we have received many requests to adjust our report to the current situation (i.e. a permanent global SLR network with few mobile systems), and to spend more attention to the quality of the data taken by the global network. The most important element of the report is the table with statistics for each individual data pass. Although the numbers will speak for themselves, we must give a warning here that some of you may be disappointed to see that their station appears to be suffering from a data problem. However, we are using a model for station positions that is already 7 years old, and which may be responsible for errors in the station position in the order of 1-5 cm. We intend to introduce a new coordinates solution in the course of this millennium. Readers of this report are invited to provide us suggestions for further improvements. ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
